According to reports, the Bobo investigation was not mentioned in court. Authorities have not said whether the assault charge is related to the disappearance of Bobo in April 2011.

According to the arrest warrant, Adams held a black revolver to the head of Amber Bray at his Holladay home and threatened to kill her. The affidavit also said that Adams pulled a knife on her while threatening to "gut" her.

Bobo was last seen on the morning of April 13, 2011, where she was seen by her brother being led away from her Darden, TN home.

The Tennessee Bureau of Investigation and Federal Bureau of Investigation began executing search warrants on Adams' home and property off Highway 69 south of Interstate 40 on Friday afternoon.

Adams had been released from the Benton County jail on Feb. 26 on drug charges.

The Jackson Sun reported that Adams did not have a lawyer at the arraignment hearing. He said he needed to contact his grandfather to arrange to hire a lawyer but had not been able to make a telephone call since Saturday night.

Decatur County officials transferred Adams to the jail in Chester County. Officials said the Decatur County jail was overcrowded.

"This investigation is about finding Holly Bobo, and the family does not want anyone to lose sight of that. Zachary Adams has, to my knowledge, not been questioned by the TBI regarding Holly Bobo's case, yet he is still incarcerated in the county jail with a minor assault charge and they have set his bail at $1 million. His brother, Dylan Adams, has been interrogated without an attorney present and held in federal holding.

"I am not here to justify my son's addiction or addictive behaviors, but he is my son who I love dearly and will continue to do so. There have been many who have been quick to jump to conclusions about my son's involvement. Let the TBI put together pieces of this investigation without any allegations and false reports of guilt.

"We want Holly Bobo found but do not want a witch hunt in doing so. To my knowledge, my son and Holly Bobo never were in the same circles. Being a drug addict does not make someone a kidnapper. I know of no motive on my son's part to have been involved or know anyone who was involved in the alleged kidnapping case."
